| MODEL485P รหัสสินค้า: 000469 รายละเอียด: Products Content:
Model485P is our top-of-the-line converters with both isolation and surge protection, enclosed terminal blocks for tamper resistance and DIP switches for configuration. Isolated power and ground generated internally. No power is drawn from the host RS-232 port. LEDs indicate data traffic. Only RS-232 side requires a power supply. Model485P is a basic isolated converter. The RS-232 side draws power from the RS-232 handshake lines of the connected PC. At least one handshake line must be asserted (high) to power the converter. If high handshake lines aren't available, Model485P is recommended. The RS-422/485 side is powered by an external power supply.
Features
1. Powered from double side, 2500V isolation, 1500W surge protection
2. Transmit distance can reach up to 1800M at the rate of 115.2kbps
3. Adopt interface atuo-adapt technology, no DIP switch setup,random switcht RS-485/RS-422 interface
4. Automatic send data control, auto distinguish and sense direction about data transfer
5. Auto sense serial signal rate, zero delay automatic transmit
